...To charge an RV battery when the RV is connected to shore power, take the + (red, positive) cable completely off the battery's terminal to be externally charged and at least wrap a dry rag around the cable end to insulate it so it can't short out by bumping into against anything. It will be a very high amperage spark if shorted out and if battery acid gasses are present in dense enough concentration, there could even be an explosion happen and acid thrown all over you....
Particularly true if you follow this advice. You should always remove the negative lead first and install the negative lead last.
